Zigbee success!

I and Fredrik successfully got genericzigbee to work today. We are now using the simplified Microchip MiWi P2P stack instead of the USB and MiWi migrated stack. We managed to toggle a LED remotely using a button and LED connected to each device. We also have to fix a bug in the MiWi P2P stack which caused a variable (ONE_SECOND) to overflow and thus prevented the node to send any packets at all. We needed to patch the PCB as well, removing the !CS control from the INT-signal.
